It may be harmful to :

•    Take Senna Tablets for too long

This is because taking too much for too long may lead to:

-    A 'lazy bowel', where the muscle in the bowel becomes too relaxed. This means that bowel emptying happens less often. This can lead to long-term constipation.

-    Imbalance of fluids and salts in the body. This can affect the tightness of muscles such as those in the bowel. It can also affect the salts in the blood.

-    Low levels of potassium in the blood (called 'hypo-kalaemia'). This can make you tired, dizzy ,make your muscles weak and cause uneven heart-beat.

-    Dehydration, making you thirsty, feel faint and giving you headaches. It can also mean you cannot pass enough urine.
